Definitions

  • the invention relates to a coupling between two shaft parts of a torsion spring shaft, preferably for sectional doors or the like, consisting of two brackets receiving the two mutually facing end regions of the shaft parts, in which the shaft parts are held in a rotationally fixed manner and via which torques from one holder to the opposite holder are portable.
  • So-called sectional gates are building gates that can be moved between an open and a closed position along at least two guide rails.
  • the opening movement of the sectional door ie the movement of the sectional door from the closed position to the open position, is supported by energy stores, namely torsion springs, which are tensioned when the sectional door is transferred from the open position to the closed position and relaxed in the opposite direction of movement.
  • These torsion springs are part of a torsion spring shaft, which is preferably arranged in the lintel area of the building opening.
  • This two-part design of torsion spring shafts made it possible in particular to have compact dimensions and easier installation conditions.
  • the two shaft parts are connected to one another by means of a coupling which has two brackets which each interact with an end region of a shaft part.
  • the two brackets are rigidly connected to one another, so that the two brackets form a component together with the connecting element.
  • the brackets are non-rotatably arranged on the two mutually facing end regions of the shaft parts, so that synchronism of the torsion springs is achieved. Tilting of the door leaf in its guides is prevented by the synchronism of the torsion springs.
  • the object of the invention is to create a generic coupling with which it is possible to connect two shaft parts of a torsion spring shaft which adjoin one another with their mutually facing end regions in a torque-transmitting manner, even though their meaning is related to them Rotation axes have a small angle to each other.
  • the solution to this problem provides for a generic coupling that the brackets can be connected to each other in such a way that a relative movement supply of the two brackets to each other is possible at least in the range of a small angle to the longitudinal axes of the shaft parts.
  • This design of a coupling according to the invention has the particular advantage that the relative movement of the two brackets relative to one another can compensate for small angles with respect to the axes of rotation of the shaft parts, as may be present, for example, due to assembly inaccuracies, local conditions and the like.
  • the two brackets are separated from one another, but are connected to one another in a form-fitting manner by means of a connecting member, so that synchronism of the two shaft parts with the torsion springs arranged thereon is ensured.
  • the transmission of the torques from one shaft part to the other shaft part is consequently carried out via the two brackets, which are each fixed to one shaft part in a rotationally fixed manner and a connecting element which positively connects the two brackets, but also a relative movement of the two brackets guaranteed relative to their axes of rotation.
  • This includes both a change in the position of the shaft parts relative to one another in the axial direction and a pivoting of one or both shaft parts from the axial direction relative to the opposite shaft part.
  • a holder is designed as a hub which can be connected in a rotationally fixed manner to a shaft part and which, with play, interacts positively with the second holder designed as a flange of a preferably hollow-cylindrical slip-on element.
  • the hub preferably has a collar on one side of which a toothed ring is arranged, the toothing of which extends essentially parallel to the longitudinal axis of the hub and, when the holder is mounted, interacts with a toothing of the flange of the second holder.
  • the hub of the one coupling part can be deflected from the coupling axis in a certain angular range relative to the associated flange of the second coupling part.
  • This alternative is achieved in that a corresponding toothed toothing between the ring gear in the area of the hub, which protrudes into the associated flange part, and one opposite the latter The corresponding toothing part of the flange is provided.
  • the toothing of the flange is preferably arranged in an opening of a flange part such that the individual teeth extend radially into the interior of the opening so that the individual teeth mesh with the ring gear of the hub collar.
  • the flange part is preferably plate-shaped and is pushed over the end of a shaft part on which the hub is subsequently placed when the coupling is mounted on the shaft parts.
  • the hub comes to lie between the flange part and the flange of the second holder, where the flange part is connected to the flange, preferably screwed.
  • a simple non-rotatable connection between the shaft parts and the brackets is achieved in that the two shaft parts each have a longitudinally extending recess into which projections arranged on the brackets engage in order to connect the brackets to the shaft parts in a rotationally fixed manner.
  • a further improvement in the connection of the shaft parts to the brackets is achieved in that the first bracket and also the hub in the region of its shell encompassing the shaft part have material thickenings which have a threaded bore through the set screws for fixing the hub on the shafts to grab.
  • the side of the collar opposite the toothed ring of the hub runs antiparallel, namely at an angle to the surface of the flange facing it, in order to enable the hub to oscillate relative to the flange.
  • this can be achieved in that the surface of the collar that faces the surface of the flange that extends radially to the longitudinal direction of the shaft parts is beveled at least in a partial area such that the collar of the hub is kept freely movable in the space existing between the flange and the flange part.
  • the free movement of the hub between the flange and the flange part is achieved in that a distance is arranged between the flange and the flange part, the axial length of which is greater than the thickness of the collar of the hub extending in the axial direction of the shaft parts. It is only important that the hub is positively connected to the flange part in every position, ie that the toothed ring of the hub engages in the teeth of the flange part in every position.
  • the toothing in the flange part has interruptions in which the material thickenings engage.
  • the interruptions in the gear ring are due to the fact that the screwing areas are provided for the shaft. Otherwise, the clutch described above still works even if some teeth are ground.
  • the large number of teeth here guarantees that, depending on the angle, a certain amount of abrasion results, which ultimately leads to a uniform pressurization of all tooth planks when torque is transmitted.
  • Figure 1 shows a coupling according to the invention in a perspective drawing of individual parts
  • FIG. 2 shows a sectional side view of two shaft parts of a torsion spring shaft connected to the coupling according to FIG. 1 and
  • FIG. 3 is a detailed representation of the coupling parts according to the
  • a clutch 1 shown in FIG. 1 consists of a hub 2 which is placed on one end of a shaft part 3 of a torsion spring shaft 4.
  • the hub 2 has a hollow cylindrical base body 5, at one end of which a collar 6 is arranged so as to stand radially outward.
  • the collar 6 has on its side facing the base body 5 a toothed ring 7 which has a plurality of teeth 8 arranged at the same distance from one another.
  • a projection 9 is arranged in the region of the collar 6, which extends into the bore of the base body 5 and interacts with a recess, not shown, in the shaft part 3, so that the hub 2 rotates with the projection 9 by means of the projection 9 engaging in the recess of the shaft part 3 Shaft part 3 is connected.
  • two material thickenings 10 are arranged on the outer surface of the base body 5 of the hub 2, which are designed as webs running in the axial direction of the hub 2 and only one of which is visible in FIG.
  • the material thickenings 10 each have a bore 11, which have an internal thread and into which set screws 12 can be screwed, with which the hub 2 is additionally fixed to the shaft part 3.
  • the coupling 1 consists of a flange 13 which has a sleeve 14 which is placed on a second shaft part 15 of the torsion spring shaft 4.
  • the sleeve 14 is also designed as a tubular cylindrical section and has two spaced-apart material thickenings 16, which are designed as webs running in the axial direction of the sleeve 14 and each have a bore 17 with an internal thread. Set screws 18 are screwed into these bores 17, with which the sleeve 14 and thus also the flange 13 are connected to the shaft part 15 in a rotationally fixed manner. Fe he the sleeve 14 has a projection 18 which extends radially into the shaft part 15 encompassing the opening of the sleeve 14 and cooperates with a recess, not shown, in the shaft part 15, so that the sleeve 14 and thus the flange 13 rotatably on the shaft part 15 are arranged.
  • both the hub 2 and the flange 13 are each connected to one end of a shaft part 3 and 15 in a rotationally fixed manner.
  • the flange 13 which extends radially outward from the sleeve 14, has three elongated holes 19 in the form of an arcuate section, which are arranged at a uniform distance from one another.
  • the coupling 1 consists of a flange part 20, which is plate-shaped and can be connected to the flange 13.
  • the flange part 20 has a circular opening 21, the edge region of which has a toothing 22 which is designed such that the individual teeth 23 extend radially into the opening 21 and axially in the direction of the ring gear 7 of the hub 2.
  • the flange part 20 has three elongated holes 24 which are designed in the shape of a circular arc and which essentially coincide with the elongated holes 19 in the flange 13.
  • the flange 13 is connected to the flange part 20 here by means of screw bolts 25 which are inserted into the elongated holes 19 and 24 and which are screwed to nuts 26.
  • the flange part 20 has interruptions 27 in the region of the toothing 22, through which the material thickenings 10 of the base body 5 of the hub 2 engage.
  • the teeth 8 of the ring gear 7 of the hub 2 in each angular position, at least partially mesh with the teeth 23 of the toothing 22 of the flange part 20, so that a torque acting on the shaft part 3 via the rotationally fixed with the shaft part 3 connected hub is transmitted to the flange part 20, from where the torque acts on the shaft part 15 via the flange 13 or the sleeve 14.
  • This configuration thus provides a relative movement of the two shaft parts 3 and 15 to one another with a constant positive connection at the same time.
  • the surface of the collar 6 facing the flange 13 extends at least in its outer edge region antiparallel to the surface of the flange 13 facing the hub 2, so that this bevel arranged in the region of the outer edge of the collar 6 has a pendulum motion allows the hub 2 relative to the flange 13.
  • the bevel and the pendulum movement are indicated in FIG. 3 by the arrow 30.
  • the axial play 28 between the hub 2 and the flange 13 also enables the shaft parts 3 and 15 to move axially with respect to one another. It is thus in the axial game 28 to a free space that allows a relative movement of the shafts 3 and 15 in the axial direction.
